The board has resigned as a whole, putting the decision in the hands of the owners, but their future will be decided on June 29th.
In the meanwhile there will be time to see how the mess evolves and, if the situation will get clearer, I guess there are some chances that the resignations won't be accepted.
One last thing: Moggi, Giraudo and Bettega are not just members of the board, but they also work for it as general director, administrator and vice-president. This means that they're still our Triade and will keep their jobs until the (new) board won't decide to fire them.
